What Do I Need For the Party?
In addition to basic SpongeBob SquarePants party supplies, like plates, cups, napkins and decorations, you may want to consider purchasing, borrowing or renting the following items for your SpongeBob party:
- SpongeBob SquarePants cartoons
- Stuffed animals or figurines of SpongeBob and his friends
- Fishing nets
- Beach balls
- Plastic fish
- A pinata
- Cut the shape of SpongeBob SquarePants, a starfish or pineapple from card stock paper.
- Cut a yellow sponge in half and glue it on white cardstock. Add googly eyes and draw on a face to create SpongeBob.
- Wash and dry old soda bottles, write your party details on a slip of paper, roll it up, and slide it inside. Make sure the paper is rolled tightly and secured so it will easily slip out of the bottle when your guests receive it. If you don’t want to make your own, purchase our invitations in a bottle.
- Wash and dry seashells thoroughly and write your party details on the back of the shells. Send them in heavily padded envelopes, or hand-deliver them to your guests.
- If you’d rather purchase invitations instead of making them, you can still have a personalized touch with our personalized Sea Sponge invitations, which will include your child’s name and all of the party details. Or you can purchase blank SpongeBob party invitations and fill in the details yourself.
Transport your guests to Bikini Bottom with these simple decoration ideas:
- Cover the ceiling, walls and floor with blue transparent cellophane wrap to give the impression of being underwater. Or hang blue streamers around the party area and from the ceiling to resemble waves.
- Scatter seashells and sand dollars around the side of the room.
- Fill the party area with bunches of blue and green balloons. Add fish mylar balloons to a few of the bunches.
- Place a bubble machine in one corner of the room.
- Create floating jellyfish using balloons with streamers attached.
- Outside, hang a sign saying “Bikini Bottom this way,” with an arrow pointing to the party area.
- Use cardboard or poster board to create underwater “street signs” to other SpongeBob sites, like Sand Mountain, Goo Lagoon, Jellyfish Fields, Kelp Forest and Mermalair.
- Hang a fish net on the wall and attach shells and fish toys, including sea horses, crabs, lobsters, etc. Or hang the toy fish from the ceiling using clear fishing line.
- Or create sea creatures like fish, starfish, shells, crabs, lobsters, etc., using cardboard paper or construction paper. Hang on your fish net or on the walls.
- Cut out flowers to look like the background on the show and hang on the walls.
- Cover the tables with blue tablecloths and decorate them with sand, faux pearls and seashells.
- Place groups of stuffed fish toys, including clown fish, angel fish, starfish, and sharks, in the corners of the party area.
- Use a large appliance box to create SpongeBob’s pineapple house or the Krusty Krab.
- Use other nautical-themed decorations like life floats, ropes and barrels.
- Put inflatable palm trees in the backyard. Surround with sand, sand pails, sea shells and other beach toys.
- Find a picture of a pirate in a magazine, or find one online and print it out. Hang it on the wall to represent the pirate in the opening credits of the show.
- Fill fish tanks with water and SpongeBob or ocean toys.
- Play SpongeBob music or episodes of the show in the background.
To keep with the underwater theme, consider serving seafood at your SpongeBob SquarePants party. Here are a few ideas:
- Fish sticks
- Popcorn shrimp
- Krusty Krab Cakes (crab cakes or hamburgers)
- Serve Goldfish crackers, Swedish Fish, and gummy sharks and fish
- Use cookie cutters to cut fish shapes out of peanut butter sandwiches, cheese slices, and deli meat slices.
- Cook seashell-shaped pasta and spinach linguini and serve chilled with butter. Call it “Seaweed & Shells Pasta.”
- Cut red licorice strings into 2″ sections and attach eight sections to a red gumball with a little red frosting. Draw on two eyes with black decorator icing to create octopus treats.
- Make “Sea Water” by coloring pitchers of apple juice with blue food coloring, and serve with fish straws.
- Bake a sheet cake and top with yellow icing. Then pipe on SpongeBob’s features to create a SpongeBob SquarePants cake.
